Here's another stumper involving eggs, but not really about eggs. A farmer is taking her eggs to market, trying to pack them neatly for sale. She notices that if she packs them in groups of two, three, four, five, or six, there is always one egg left over. But if she packs them in groups of seven, they are all in complete groups with no eggs left over. So how many eggs does she have? There's more than one answer, so find the smallest. What do they all have in common? Hint: think about factors and remainders!
